Hi Galen, I am sorry that you are having problems with this. I just tried to do this conversion and it all worked.
Step 1. Download a solid .STL from Thingiverse (or create your own.)
Step 2. Open .STL in CURA 15.04.4 . It MIGHT work in other versions of CURA but my script is looking for specific gcode wording.
Step 3. Save the gcode.
Step 4. From gCodeToSVG.html , select your gcode and upload, then set your parameters, then click on "process gcode. You should now see a page that starts with “<?xml version”
At this point, you can either:
Select all, copy, paste into a notepad, save as “MySVG.svg”
Do a File, save page as “MySVG.svg”
At this point you should now have a file called “MySVG.svg”
Make sure your computer did not append a .txt or somesuch. Make sure that the file is a dot svg.
Now test the SVG:
Open a file explorer or finder and locate the folder or directory where your “MySVG.svg” lives. You should now be able to open it in one of several ways:
Right click on it and select “open in browser” (or more specifically “open in firefox” or “open in chrome”
You can also try to right click and choose “open in Inkscape” or “open in Illustrator”
On my computer, if I have it set to view files as icons, I can see if the svg is ok without even opening, because the icon or tile is a small version of the image.
So, at this point you should have an SVG file. It should look like a grayscale image. If so, open in Easel.
Like I said, I tested the pipeline today, it works and Easel opened the resultant SVG.
If it doesn’t work for you, please let me know. I will TRY to be responsive. Some of my workdays are long, there is also a lot of dadding and family time. And I am frequently in places of poor connectivity. But let me know this works for you.
